[PATCH 02/13] libata: separate ATA_EHI_DID_RESET into DID_SOFTRESET and DID_HARDRESET

[Tejun Heo <htejun@gmail.com>]

Separate ATA_EHI_DID_RESET into ATA_EHI_DID_SOFTRESET and
ATA_EHI_DID_HARDRESET.  ATA_EHI_DID_RESET is redefined as OR of the
two flags.  This patch doesn't introduce any behavior change.  This
will be used later to determine whether _SDD is necessary or not.
